Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a massage chair according to an embodiment of the present invention. FIG. 2 is a perspective view of a massage device according to a first embodiment of the present invention. And a seat plate 20 on which the user can sit. The back plate 10 and the seat plate 20 are fixed to and supported by the left and right support frames 11 of the massage chair.

As shown in the drawing, a support frame 11 extending from both sides of the back plate 10 to the left plate 20 is disposed. A working space 10a is formed between the support frames 11, The pair of massage rollers 40 are provided so as to move up and down to provide vibrating massage to the back, back, and shoulder portions.

The massage chair (1) provided in the present invention is characterized in that the backrest section (10) is provided with the upper body stretching section (50) for the upper body stretching effect.

The upper body stretching part 50 is provided with a hand lever 51 which is operated to move up and down by a driving force behind the back part 10 of the massage chair 1 so that the foot part 30 provided at the front lower part of the massage chair is forward When the hand lever 51 is moved up and down, the hand lever 51 is also lifted up to provide a stretching motion in which the joints and muscles of the upper body are relaxed while holding the hand lever 51 with both hands as shown in FIG. It is installed to do.

The driving unit for moving the hand lever 51 up and down will be described. 2, a lifting pin 54 is slidably engaged with a shaft portion 53 formed at the center of the upper side of a mounting plate 55 fixed to the back of the backing plate 10, Is connected to the hand lever 51. [0050]

A screw 56 supported by a bearing 57 built in a pin housing 59 at the center of the lower portion of the mounting plate 55 is provided at a lower portion of the lift pin 54, ) Screw into the inner center. Accordingly, when the screw 56 rotates, the lifting pin 54 ascends or descends according to the rotating direction, and the hand lever 51 moves up and down.

3, the lower side of the screw 56 for moving up and down the hand lever 51 is connected to the electric cable shaft 58, which is connected to a separate driving motor M ) To operate. The electric cable shaft 58 is a flexible wire cable for transmitting the rotational driving force of the motor and is a general power transmitting means.

The structure in which the threaded rod 54a is formed on the upper side of the lifting pin 54 and screwed to the hand lever 51 is used for finely adjusting the height H of the hand lever 51 It is means.

The elevation height H of the hand lever 51 can be arbitrarily set by the user so as to operate in accordance with the user's body conditions and the switch 51a is installed on both sides of the hand lever 51, So that the hand lever 51 is moved up and down.

For example, when the one-way switch 51a is pressed, the first switch 51a is depressed and the second switch 51a is depressed. The setting may be performed by using a measuring device such as an optical sensor or a rotary encoder, You can also set and control.

When the footrests 33 for hanging both feet of the user are formed on the front lower side of the massage chair 1, both feet are caught and fixed by the footrests 33 when the upper body stretching part 50 is lifted up, But can stretch throughout the body.

And a foot part (30) for providing a massage function to the feet and the calf by shrinking or expanding the air tube while accommodating the feet and legs of the user to the lower side of the massage chair, wherein the foot part 30 can be moved back and forth.

When the footrest 30 advances forward in a state where the user is seated, the hand lever 51 is also elevated to a predetermined height at the upper portion. In order to stretch the footrest 30, The air tube that massages the calf and feet is inflated so that the stretching movement is performed when the legs and feet are firmly supported.

When a double shaft motor or the like is used as the driving motor M, it is possible to implement the lifting and lowering operation of the upper body stretching part 50 and the forward and backward movement of the footrest part 30 by one motor as shown in FIG. 3 Examples of the driving method will be specifically described below.

As described above, the massage chair provided in the present invention is provided with an upper body stretching portion 50 which is vertically lifted and lowered at the rear of the massage chair, so that the whole body stretching motion is possible. Conventional massage chairs merely provide a massage function for rubbing the calf and the foot around the foot by using the air pressure in the footrest 30 together with the massage of the waist by the hitting and pressing of the massage roller 40, The effect could not be expected.

In particular, when the footrest 30 and the upper body stretching unit 50 are configured to protrude simultaneously, the hand lever 51 is lifted while the hand lever 51 is held with both hands as shown in the state of use in FIG. 4, At the same time, since the lower half body is pulled forward due to the advancement of the foot part (30), the upper and lower half bodies are pulled up and down at the same time to relax the muscles, thereby relieving the muscle tension and helping to recover fatigue and increase the flexibility of the joint .
